A clear, practical guide to when a boat trailer in Queensland actually needs a safety certificate, how single vs dual-axle rules work, and how Anchorpoint Boat Buyers can handle the process for you.
Light trailers under 750 kg ATM generally don’t require a safety certificate. Most boat trailers above that weight – especially dual-axle rigs – will. Anchorpoint Boat Buyers can check your setup and manage the paperwork for you.
In QLD, boats themselves don’t need a safety certificate. The rules apply to the trailer that’s being sold, transferred or newly registered.
Single-axle trailers are often lighter, but once your trailer’s ATM is above 750 kg – very common with fibreglass hulls and dual-axle rigs – safety certificate and brake rules kick in.
As part of our buyers’ agent service, Anchorpoint Boat Buyers can check compliance, organise mobile inspections, and coordinate TMR registration so you don’t have to navigate it alone.
The short answer: no – boats themselves do not require a safety certificate in Queensland.
Roadworthy and safety certificate requirements apply to the trailer, because the trailer is what uses the road. When people talk about “boat roadworthy”, they’re really referring to the boat trailer.
